  • Patent number: 10585759
    Abstract: Resynchronization of folders shared among multiple client devices over a network is provided. Metadata and hash values stored on the client device are moved from a metadata database to a resynchronization database, and the data in the metadata database is deleted. Metadata is created for locally stored synchronized files. For each file, the created metadata is compared to the metadata stored in the resynchronization database. If the metadata matches, hash values are retrieved from the resynchronization database and stored with the created metadata in the metadata database. If the metadata does not match, hashes for the file are created and stored with the created metadata in the metadata database. A synchronization operation may be performed which consists of comparing the files stored on the client to the synchronized versions on a host server and updating or adding files that are not present or not up to date.

  • Patent number: 6056066
    Abstract: An apparatus for regenerating compacted soil in reclaim surface mining lands is provided. The apparatus includes an auger rotatably mounted above and forward of the blade of an earthmover, such as a bulldozer. The auger is longer than the blade and is mounted such that it extends substantially beyond one side of the blade. Adjacent this extension, a controllable lateral baffle is mounted for selectively adjusting a transverse dimension of the blade. In operation, compacted soil is collected by the blade until it reaches the auger. The auger then decompacts, transversely displaces, and deposits the soil relative to the blade, thereby creating a decompacted rooting layer that is ideal for planting. The lateral baffle may be selectively adjusted during operation to control the level of deposition of decompacted soil to provide a substantially level berm. A method of soil regeneration using the apparatus of the present invention is also disclosed.

The respective transducers in turn are each connected in circuit with an associated driving member wherein one of the driving members is operatively connected to the vehicle to effect the drive thereof; and the other driving member is operatively connected to the implements to effect the drive thereof, whereby the power provided by the primary source can be selectively and variably applied to either the vehicle and the implements as the vehicle is driven.

  • Patent number: 4023510
    Abstract: A depth control and protective apparatus is disclosed as particularly useful in a tillage assembly for sod seeding purposes. The apparatus includes a pair of skids mounted upon a pivoted arm, which arm has also mounted thereon a pair of cutter wheels for cutting a furrow in ground to be seeded, each skid including a ground engaging portion to determine the maximum depth of furrow cut by the cutter wheel. Each skid is mounted for essentially vertical movement with respect to the associated arm and cutter wheel mounted thereon to thereby determine and control the depth of furrow cut by the associated cutter wheel. A substantially circular plate has an oval aperture in the central portion through which the axle and drive for the cutter wheel extends, and an inwardly directed cylindrical flange extends to the periphery of the circular plate to protect the axle and to provide for movement of the skid relative to the cutter wheel and axle.

  • Patent number: 3983943
    Abstract: A combination implement has a leading cultivator with fixed tines and a rear rotary harrow with driven soil working tined members. The cultivator has side ground wheels with vertical adjusting means that controls the working depths of the fixed tines. The harrow has a trailing roller that is interconnected to the harrow frame with arms that also have an adjustment feature so that the working depths of the harrow's tined members can be regulated. The cultivator and harrow are linked to one another by a parallelogram linkage so that they can be disconnected from one another and individually connected to the three point lift of a prime mover. When the combination is assembled, a suspended drive shaft of the harrow's driving system is passed through the cultivator and connected to the p.t.o. of the prime mover.
